  • Publication number: 20140098314
    Abstract: The present invention provides a liquid crystal medium composition and a liquid crystal display panel manufactured with same. The liquid crystal medium composition includes a negative type liquid crystal material, a polymerizable monomer, a sensitizer, and stabilizer. The sensitizer is an organometallic complex that has an amount of 0.01%-5% of total mass of the liquid crystal composition and has a strong absorption of ultraviolet light having a wavelength of 300-450 nm. The sensitizer converts the primary wavelength range of ultraviolet light for reaction of the polymerizable monomer from 200-300 nm to 300-450 nm, staying away from the absorption band of the liquid crystal material and reducing damages caused on the liquid crystal material and the alignment material of polyimide, thereby heightening reaction efficiency and homogeneity of the polymerizable monomer and the quality and lifespan of the liquid crystal display panel.

  • Patent number: 8446536
    Abstract: A multi-domain vertical alignment liquid crystal display that does not require physical features on the substrate (such as protrusions and ITO slits) is disclosed. Each pixel of the MVA LCD is subdivided into color components, which are further divided into color dots. Each pixel also contains extra-planar fringe field amplifiers that separate the color dots of a pixel. The voltage polarity of the color dots and extra-planar fringe field amplifiers are arranged so that fringe fields in each color dot causes multiple liquid crystal domains in each color dot. Specifically, the color dots and fringe field amplifying regions of the display are arranged so that neighboring polarized elements have opposite polarities.

  • Patent number: 8436965
    Abstract: External light is reflected due to a difference in refractive indices of a black matrix and a glass substrate. When the black matrix is a black resin, there is a difference in refractive indices of the black resin and a first substrate. Also, there is a difference in refractive indices of the colored layer and the first substrate. Therefore, external light is slightly reflected. There is a problem in that the reflected light reduces contrast. A structure in which one polarizing element having dichroism is interposed between a pair of substrates is employed, and a light interference layer is provided between a color filter and a glass substrate, whereby a difference in refractive indices is moderated to reduce light reflection.
